Description

Bending furnace
Technical field
The utility model relates to a kind of equipment of glass bending processing, particularly the equipment of the hot bending of windshield processing.
Background technology
In the prior art, a kind of bending furnace that is used for the production of shield glass is arranged, it mainly comprises the framework that is cuboid, has been horizontally disposed with lifting gantry in the framework, and the framework both sides are respectively equipped with two sprocket wheels, frame mid portion is positioned at the sprocket wheel top and is provided with rotating shaft, rotating shaft is provided with four capstan winches, is in transmission connection main motor and framework relative fixed between the output shaft of rotating shaft and main motor, installed around chain on the capstan winch respectively, each chain correspondence is one by one walked around respective sprocket and is connected with lifting gantry; Be positioned at the lifting gantry top in the framework and horizontal fixed is provided with some electric stove wires.This device is mainly used in the hot bending of shield glass, during its work, the mould that will be used for hot bending is placed on lifting gantry, the profile of mould is made progress, above the profile of mould, place the workpiece that cuts, be sheet glass or preformed glass, main then motor rotates, chain is on capstan winch, make lifting gantry rise to position near electric stove wire, the electric stove wire heating power makes glass softening, and the glass after softening can be smooth on the profile of mould, the hot bending end of processing is taken out in the cooling back.Its weak point is: produce in the deformation process at sheet glass, the part of glass can be gradually away from electric stove wire, and the spacing between other part and electric stove wire changes not quite, cause local temperature on glass inhomogeneous, the spherical transition that causes glass in moulding process easily is not slick and sly, influences quality product; In addition, because the local stow away from heat of glass needs to consume more heat energy and just can be processed into type, can cause energy consumption to increase.
The utility model content
The purpose of this utility model provides a kind of bending furnace, and electric stove wire can be changed with the distortion of workpiece, when improving the quality of products, cuts down the consumption of energy.
The purpose of this utility model is achieved in that bending furnace, comprise the framework that is cuboid, be horizontally disposed with lifting gantry in the framework, the framework both sides are respectively equipped with two sprocket wheels, and frame mid portion is positioned at the sprocket wheel top and is provided with rotating shaft, and rotating shaft is provided with four capstan winches, be in transmission connection between the output shaft of rotating shaft and main motor, main motor and framework relative fixed have installed around chain respectively on the capstan winch, each chain correspondence is one by one walked around respective sprocket and is connected with lifting gantry; Be positioned at the lifting gantry top level of going back in the framework and be provided with some electric stove wires; Described electric stove wire two ends are suspended in the drag-line lower end, frame roof be provided with some that parallel and with electric stove wire drum shaft one to one, corresponding two cylinders that are provided with the electric stove wire two ends on each drum shaft, the drag-line upper end installs around on respective rollers, and drum shaft end and stepper-motor are in transmission connection.
This device is during work, and stepper-motor can drive electric stove wire and move downward in real time according to the distortion situation of workpiece, like this, can keep the spacing between the part that needs deformation of electric stove wire and workpiece to equate that workpiece is heated evenly, and can not cause the spherical transition inequality; In addition, can reduce energy consumption in the hot bending process.Compared with prior art, the utility model can improve the quality of products, and reduces production energy consumption.The utility model not only can be used for the hot bending of shield glass, and the hot bending that also can be used for other special-shaped glass is made.
Be to reduce the use of stepper-motor, reduce manipulated variable, each stepper-motor correspondence two drum shafts that are in transmission connection.Adjacent two electric stove wires are when Workpiece shaping, and its position is little with the relative variation of distance, and these two groups of pairing drum shafts of electric stove wire are driven by same stepper-motor, to reduce manufacturing cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Wherein, 1 capstan winch, 2 main motors, 3 stepper-motors, 4 drag-lines, 5 sprocket wheels, 6 chains, 7 electric stove wires, 8 workpiece, 9 moulds, 10 lifting gantrys, 11 frameworks, 12 rotating shafts, 13 drum shafts, 14 cylinders.
Embodiment
As figure, be bending furnace, comprise the framework 11 that is cuboid, be horizontally disposed with lifting gantry 10 in the framework 11, framework 11 both sides are respectively equipped with two sprocket wheels 5, framework 11 middle parts are positioned at sprocket wheel 5 tops and are provided with rotating shaft 12, rotating shaft 12 is provided with four capstan winches 1, is in transmission connection between the output shaft of rotating shaft 12 and main motor 2, main motor 2 and framework 11 relative fixed, installed around chain 6 on the capstan winch 1 respectively, each chain 6 correspondence is one by one walked around respective sprocket 5 and is connected with lifting gantry 10; Be positioned in the framework 11 lifting gantry 10 tops also level be provided with some electric stove wires 7; Described electric stove wire 7 two ends are suspended in drag-line 4 lower ends, framework 11 tops be provided with some that parallel and with electric stove wire 7 drum shaft 13 one to one, corresponding two cylinders 14 that are provided with electric stove wire 7 two ends on each drum shaft 13, drag-line 4 upper ends install around on respective rollers 14, and drum shaft 13 ends and stepper-motor 3 are in transmission connection; Each stepper-motor 3 correspondence two drum shafts 13 that are in transmission connection.
